Abstract

The invention discloses a preparation method of a high-glossiness wear-resistant impregnated paper, and belongs to the technical field of preparation of decoration paper. The method is characterized in that alumina powder surface is effectively modified through xylene formaldehyde resin, and an oleophylic structure of a dimethyl benzene ring is introduced into a molecular structure of the aluminapowder, and thus the hydrophobicity of the alumina powder can be improved; in addition, the carbon black has certain chemical activity and is provided with a plurality of surface activation points, sothat the carbon black easily reacts with mixed powder during stirring. According to the method, paraformaldehyde solution, melamine, polyvinyl alcohol and citric acid are mixed and stirred and reactunder certain temperature to obtain melamine formaldehyde resin; the melamine formaldehyde resin is modified through epoxy chloropropane; in addition, epoxy chloropropane is added to a base material;hydroxide radical in the base material easily reacts with an epoxide group of epoxy chloropropane to generate an ether bond, and thus the hydroxide radical cannot be further oxidized during curing, and as a result, the glossiness of the impregnated paper can be improved; the method has a good application prospect.

Description

technical field [0001] The invention discloses a method for preparing high-gloss wear-resistant impregnated paper, which belongs to the technical field of decorative paper preparation. Background technique [0002] Impregnated paper is made of non-woven wood pulp mixed with PE and plant fibers. Ultra absorbent and solvent resistant while also being a very economical low particulate release tissue. It is widely used in the veneer of cabinets, wardrobes, and Bell laminate flooring. After the veneer paper is impregnated with melamine glue and some additives, it is melamine impregnated paper. And boards (density board, particle board, plywood), after hot pressing of steel plates in hot presses, they become decorative boards. Melamine-impregnated paper varies according to the function of the base paper. If you want to achieve a decorative effect, then use patterned paper; if you want to achieve a wear-resistant effect, then use wear-resistant paper; if you want to achieve a me...
